Wolfram Study Groups (WSG) are a new special program, set up to be fun, directed and incremental online learning resources. There is something for everyone, whether you are a student, an educator/parent looking for quality resources, or an adult interested in learning new skills. The group that is getting started now offers a daily opportunity to meet online with others interested in building Wolfram Language skills. Each session will include short lesson videos from the interactive course An Elementary Introduction to the Wolfram Language, based on Stephen Wolfram’s book, with experts on hand to explain concepts in more depth. We plan to include multiparadigm data science and other application topics too. Sessions run Monday through Friday, 12-1pm US EDT (4-5pm GMT). A certificate of program completion will be awarded to participants who attend online sessions and pass auto-graded online quizzes. Sign up and receive email reminders of upcoming sessions, or join a session in progress.

Correct, no Study Group today. Instead, we encourage everyone to attend the New in Wolfram Language 12.1 webinar, starting at 12pm US EDT (5pm GMT) today. Jon McLoone will share an engaging overview presentation with us, and we’ll dive into specific topics in detail at upcoming Wednesday webinars. Join by logging in here: https://wolfr.am/LOBWol90

I do have 2 questions, I tried doing get data from the internet like “lily” the flower, but it was a mess: here is the example tried.How does one actually get images of the flower "lily"as an example.

Import["<a href=“https://images.search.yahoo.com/search/images;https://images.search.yahoo.com/search/images;ylt=\ A0geKLottpVe0NMA0RRXNyoA;_ylu=\ X3oDMTE0cTZhamZ0BGNvbG8DYmYxBHBvcwMxBHZ0aWQDQTA2MjJfMQRzZWMDcGl2cw–?\ p=lily&fr2=piv-web&fr=mcafee”]

My other question is there a command to to get the color coordinate function. Looking to get this plot

For your first question you want to modify the code as follows:

Import["https://images.search.yahoo.com/search/images;_ylt=AwrExo6gMpdei08AnAmLuLkF;_ylc=X1MDOTYwNTc0ODMEX3IDMgRmcgMEZ3ByaWQDMkFybVJzZFBSbmVtRGs0aHVwdU1oQQRuX3N1Z2cDMTAEb3JpZ2luA2ltYWdlcy5zZWFyY2gueWFob28uY29tBHBvcwMwBHBxc3RyAwRwcXN0cmwDBHFzdHJsAzQEcXVlcnkDbGlseQR0X3N0bXADMTU4Njk2NzIwNQ--?fr2=sb-top-images.search&p=lily&ei=UTF-8&iscqry=&fr=sfp","Images"]

To look for images at a URL, use the “Images” option with Import:

Import[<URL>,"Images"]

For your second question: you may want to look at ChromaticityPlot: Chromatic diagram in 2D—Wolfram Documentation

Hello Abrita, Excellent , Thank you very much. Just tried it and it works like a charm. I will compare the 2 commands and see how you modified them.
